Description
Technical field
The present invention relates to the waste emulsified mixture treatment process for combining ultrasonic wave and electrocoagulation.
Background technique
Electrocoagulation is widely used in always the processing of various industrial sewage from after the proposition of early stage in 20th century.Electrocoagulation
Reaction principle is using metals such as aluminium, iron as anode, and under the action of direct current, anode is dissoluted, and generates Al, Fe plasma,
A series of oxidation process through hydrolysis, polymerization and ferrous iron develops into various hydroxo complexes, multinuclear hydroxo complex so that hydrogen
Oxide, make the colloidal state impurity in waste water, suspended impurity coagulative precipitation and separate simultaneously, the contaminant particle of electrification is in electric field
Middle swimming, Partial charge are neutralized by electrode and it are promoted to take off steady coagulation.
When waste water carries out electrolytic flocculation processing, not only there are coagulative precipitation effect, Er Qieyou to colloidal state impurity and suspended impurity
In the oxidation of anode and the reduction of cathode, multiple pollutant in water removal can be removed.
Ultrasonic technology is applied at present in water treatment field macromolecular substances degradation process, especially processing high molecular weight
The degradation effect of polymer is more significant.Mechanical effect, cavitation effect and fuel factor of the ultrasonotomography derived from ultrasound.
Metal and its alloy material are required during being processed into various component of machine using various lubricants.Chipless
Metal forming lubricant, the lubricant for having bits forming process to use is known as cutting lubricant the lubricant that forming process uses.
Metal working lubricant is divided into oil type and aqua type two major classes.Oil type lubricant includes soluble oil, semi-synthetic liquid and conjunction
At three kinds of liquid.Wherein soluble oil is also known as emulsion, it is formed by oil contents such as mineral oil with surfactant formulatory, mainly at
Dividing has: oiliness additive such as vegetable and animals oils, fatty acid and its soap, fatty alcohol etc.；Rust-inhibiting additive for example barium mahogany sulfonate, petroleum,
Sodium sulfonate, alkenyl succinic acid etc.；Hydrotropy additive such as butanol, phthalic acid vinegar etc.；Emulsifier has the mahogany acid of anionic
Sodium, oleic acid receive soap etc., non-ionic polyoxyethylene aliphatic alcohol ether etc.；Emulsion stabilizer has ethylene glycol, n-butanol etc..It is wherein newborn
Agent (surfactant) is the critical substances that cutting fluid is configured to stable emulsion.Emulsion waste liquid COD is up to 6000--
10000mg/L, oil content 3000--5000mg/L, PH7--9, SS800--1200mg/L.Flushing water, hand-washing water etc. is discharged also in workshop
Containing lubricating fluid, emulsion etc., concentration is lower (oil-containing < 100mg), belongs to weak solution.
The technology in terms of waste emulsified mixture processing has the conventional treatments works such as air bearing coagulation+biochemical treatment, burning disposal at present
Skill.
Air bearing coagulation+biochemical treatment enters biochemical treatment system with other waste water using after air bearing, coagulating sedimentation together, by
Low in emulsion oil removal efficiency, petroleum substance has stronger inhibiting effect to biochemical system, and mixed waste water is often to life
Change system generates impact and deleterious effects.The technique be a kind of earliest technique of waste emulsified mixture processing in the steel industry of early stage and
Metal cutting industry has application, but with the continuous improvement of factory's emulsion type increased with environmental protection standard, the technique is
It does not use.
Summary of the invention
The purpose of the present invention is to provide the waste emulsified mixture treatment process for combining ultrasonic wave and electrocoagulation, it is intended to utilize super
The good demulsification degradation effect that sound wave has emulsion in some frequency band improves the treatment effeciency of subsequent electrocoagulation.
To achieve the goals above, the technical scheme is to design the waste emulsified mixtures for combining ultrasonic wave and electrocoagulation
Treatment process, comprising the following steps: waste emulsified mixture is passed first into ultrasonic treatment slot, adjusting PH is 6 ~ 8, in set supersonic frequency
Lower processing several hours will carry out demulsification degradation；It is pumped into electrolytic cell after then waste emulsified mixture is filtered, while electrolyte chlorination is added
Sodium, and adjusting waste emulsified mixture PH is 5.5 ~ 6.5, is powered into electrolytic cell, after cell reaction, staticly settling will be on liquid level after 1h
Suspended oil strikes off, and supernatant water is the draining handled well.
Preferably, stage, supersonic frequency 21KH are ultrasonically treated.
Preferably, it is ultrasonically treated the stage, adjusting waste emulsified mixture PH is 7.
Preferably, sonication treatment time is 1.5 hours.
Preferably, sodium chloride additional amount is 1.25g/L, and it is 6 that waste emulsified mixture PH is adjusted in cell reaction.
Preferably, Faradaic current intensity is 4mA/cm2。
Preferably, electrolysis time 40min.
Preferably, it is 120cm that the battery plate of the electrolytic cell, which is surface area,2Aluminium sheet, spacing 1cm, yin, yang pole plate exists
Distribution multiple groups are spaced apart from each other in electrolytic cell.
In method of the present invention, waste emulsified mixture is handled using ultrasonic wave and electrocoagulation, influences processing effect
The factor of fruit mainly have waste water pH value, supersonic frequency, sonication treatment time, current strength and electrolysis time, sodium chloride dosage with
And pole plate spacing etc..The present invention passes through many experiments room and small-scale experiment, collects a large amount of basic datas, determines in above every fortune
Under the conditions of row, the present invention can have optimization process effect.
The advantages and beneficial effects of the present invention are: 1, with supersonic gas vibrating technology, in the oscillation of specified frequency of oscillation
Under, oily substance dissipates solution in waste emulsified mixture, is demulsified, and floating forms oil slick layer；A part of organic matter by space at small molecule,
